This is a Plain English Papers summary of a research paper called AI Math Models Score Under 5% on Olympic Math Proofs, Despite High Answer-Only Scores. If you like these kinds of analysis, you should join AImodels.fyi or follow us on Twitter.
Overview
- Recent LLM benchmarks show impressive performance on math competitions when judged on final answers only
- New research evaluated full mathematical reasoning abilities on 2025 USAMO problems
- All tested models performed poorly, scoring under 5% when evaluated on complete solutions
- Evaluation revealed significant gaps between final-answer performance and rigorous mathematical reasoning
- Common failure modes identified include training artifacts and inability to construct valid proofs
- Results suggest current LLMs are inadequate for complex mathematical reasoning tasks
Plain English Explanation
AI models have gotten really good at answering math competition problems - if you only look at their final answers. A new paper shows these models are actually far worse than they appear when you evaluate their entire reasoning process.
Think of it like this: if someone gives ...
